Playing for John Williams and Paul McCartney? That’s what Pittsburgh Symphony Orchestra guest violinist Josefina Vergara does on a regular basis living in Hollywood as a member of the Los Angeles Chamber Orchestra. She’s a frequent player with the PSO and she’s joining them on this European tour. Jim Cunningham caught up with Josefina and PSO Trumpet Neal Berntsen to talk about the tour, the type of trumpets being used on the Mahler and how this tour is making them feel like a sense of normalcy is returning.
